Abstract

We synthesize, in situ, W-x wt% Cu (x = 5, 10, and 20 wt%) composite nanoparticles using inductively coupled radio-frequency (RF) thermal plasma. In the RF thermal plasma process, the W-x wt% Cu composite nanoparticles are synthesized by hydrogen reduction of tungsten trioxide (WO3) and cupric oxide (CuO). The synthesized W and Cu nanoparticles are effectively reduced to W and Cu, and the W-Cu nanoparticles are uniformly distributed bimetallic (or composite) nanoparticles.
